That's OK and fair I think, even as a European. HN is fairly US-centric, both submissions, users and comments. I think after more than a decade here, you get to used to everyone assuming you're American and capitalist by default, which given the company who owns HN, kind of makes sense ;)

I like the adjacent conversations just as much, or more.

We(?) more or less want this to be a place of general curiosity,

perhaps revolving loosely around those things, but not tightly clung to them.
